RE: What *are* they smoking?
And then Verisign starts using multiple IP addresses and rotating through them. And then they stop giving any other clues that it is a wildcard record. Great. Just what we need... To be in an escalating war with the people running the root nameservers. Since it is clearly in Verisign's business interest to make it impossible for you to tell when you've been handed one of the wildcard replies, I don't see this stopping any time soon.
